Like most people have said, it's a nice idea, but in reality would probably cause problems and take some of the fun out of things. Besides, as the saying goes, one man's meat is another man's poison, so there would be plenty of disagreements on who was deserving of a win and who wasn't. Plus, with art (and that's what we do here) being subjective, it's very difficult to say any one pic is "the best".
